LMFBO

For men, we have LMFBO, laughing my fucking balls off, but for women, we have... LAUGHING MY FUCKING BOOBS OFF!

Used in texting by teenage kids, and an abreviation for: Laughing My Fucking Boobs Off

Girl 1- "Look at this post on Instagram"

*they see the post about a cat banging their head on a sink*

Girl 2- "LMFBO!!!! LOL!"
